Does anyone know what happened to SUMO Electronics?

Jim Bongiorno, the founder of SUMO and GAS, died in January 2013.

RIP James Bongiorno.   One of the truly great engineers is no more.

Randy Patton last owned Sumo.... Rich May took over design after Jim died, He designed the Andromeda II and Polaris. Jason Stoddard was one of their last product designers,  Jason Did Polaris III, Andromeda III Athena II.  Randy had PS Audio, Meitner, Threshold and Sumo.  He sold off what he could and closed down the rest.  

Curiousjim…no problemo, and full disclosure (!), I bought a Freya last November and it's a fun thing that's great for tube rolling. Also Stoddard wrote a book (or made a book out of a book length bunch of posts) about his adventures in the audio biz…haven't read it but I might.

I have an original Athena and Andromeda from when James Bongiorno ran the company. After he left later versions may not have been as good! Sumo closed long before James died!
